System and method of preventing alteration of data on a wireless device
View Patent ↗A system and method for securing data on a wireless device. A secured zone is defined by a boundary sensor. A data processing system is coupled to the boundary sensor and a wireless device. If the data processing system detects that the signal strength of the wireless device has fallen below a first predetermined value for longer than a second predetermined value, the data processing system deletes a digital certificate corresponding to the wireless device from memory. Thus, when the wireless device is reintroduced into the secured zone, in response to determining that a digital certificate corresponding to the wireless device is not stored in memory, the disabling module disables the wireless device from operation within the secured zone.
1. A system for securing data, comprising:
at least a wireless device;
a data processing system, coupled to said at least a wireless device, wherein said data processing system disables said at least a wireless device in response to determining that an emitted signal strength of said at least a wireless device is less than a first predetermined value for greater than a period of time represented by a second predetermined value; and
a memory for storing at least a digital certificate corresponding to said at least a wireless device to authenticate communication from said at least a wireless device, wherein said digital certificate is removed from said memory in response to determining said emitted signal strength of said at least a wireless device is less than said first predetermined value for greater than said period of time represented by said second predetermined value.
2. The system according to claim 1 , wherein said data processing system further comprises:
a signal detector for measuring said emitted signal strength of said at least a wireless device; and
a timer for determining whether said emitted signal strength of said at least a wireless device is less than said first predetermined value for greater than said period of time represented by said second predetermined value.
3. The system according to claim 1 , wherein said data processing system further comprises:
a disabling module for disabling said at least a wireless device in response to determining said memory does not include said at least a digital certificate corresponding to said at least a wireless device.
4. A method for securing data, comprising:
detecting an emitted signal strength from at least a wireless device;
in response to determining said emitted signal strength from said at least a wireless device is less than a first predetermined value for greater than a period of time represented by a second predetermined value, disabling said at least a wireless device; and
storing, in a memory, at least a digital certificate corresponding to said at least a wireless device to authenticate communication from said at least a wireless device, wherein said digital certificate is removed from said memory in response to determining said emitted signal strength of said at least a wireless device is less than said first predetermined value for greater than said period of time represented by said second predetermined value.
5. The method according to claim 4 , further comprising:
measuring said emitted signal strength from said at least a wireless device; and
determining whether said emitted signal strength from said at least a wireless device is less than a first predetermined value for greater said period of time represented by said second predetermined value.
6. The method according to claim 4 , said disabling further comprises:
in response to determining said at least a digital certificate corresponding to said at least a wireless device is not present in said memory, disabling said wireless device.
7. A computer program product, residing on a computer usable non-transitory storage medium, comprising:
program code to detect an emitted signal strength from at least a wireless device;
program code to disable said at least a wireless device, in response to determining said emitted signal strength from said at least a wireless device is less than a first predetermined value for greater than a period of time represented by a second predetermined value;
program code to store, in a memory, at least a digital certificate corresponding to said at least a wireless device to authenticate communication from said at least a wireless device, wherein said digital certificate is removed from said memory in response to determining said emitted signal strength of said at least a wireless device is less than said first predetermined value for greater said period of time represented by said second predetermined value.
8. The computer program product according to claim 7 , further comprising:
program code for measuring said emitted signal strength from said at least a wireless device; and
program code for determining whether said emitted signal strength from said at least a wireless device is less than a first predetermined value for greater said period of time represented by said second predetermined value.
9. The computer program product according to claim 7 , said disabling further comprising:
in response to determining said at least a digital certificate corresponding to said at least a wireless device is not present in said memory, disabling said wireless device.
